655 New Linux libpcap implementation, which, in 2.2 and later
656 kernels, uses PF_PACKET sockets and supports kernel packet
657 filtering (if compiled into the kernel), and supports the "any"
658 device for capturing on all interfaces. Cleans up promiscuous
659 mode better on pre-2.2 kernels, and has various other fixes

664 an interface, to allow interfaces to be opened by interface name.
666 libpcap savefiles have system-independent link-layer type values
667 in the header, rather than sometimes platform-dependent DLT_
668 values, to make it easier to exchange capture files between
671 Non-standard capture files produced by some Linux tcpdumps, e.g.
672 the one from Red Hat Linux 6.2 and later, can now be read.
674 Updated autoconf stock files.

677 protocols, and work on Token Ring (with non-source-routed

686 Removed Linux specific headers that were shipped.
688 Security fixes: Strcpy replaced with strlcpy, sprintf replaced
691 Fixed bug that could cause subsequent "pcap_compile()"s to fail
692 erroneously after one compile failed.
694 Assorted other bug fixes.
696 README.aix and README.linux files added to describe
697 platform-specific issues.
699 "getifaddrs()" rather than SIOCGIFCONF used, if available.
